Title:
ACOUSTIC WAVE-BASED IMAGE ADVERSARIAL EXAMPLE GENERATION METHOD, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/083599
Kind Code:
A1
Abstract:
Disclosed are an acoustic wave-based image adversarial example generation method and a system. The method comprises: obtaining a picture containing a target object or a target scenario; with respect to the obtained picture, utilizing an acoustic wave adversarial example simulation model to generate a simulated image example having an adversarial effect on a deep learning algorithm in a target machine vision system; utilizing an adversarial example optimization method to optimize the generated simulated image example, and obtaining a maximally optimal adversarial example as well as a corresponding adversarial parameter; utilizing an inertial sensor reading injection method and injecting the adversarial parameter into an inertial sensor of the target machine vision system by means of an acoustic wave, causing the adversarial parameter to become a sensor reading, and said sensor reading triggering an image anti-shake module in the target machine vision system to operate, so as to generate a specific blur pattern in a generated real picture, and thereby generating an image adversarial example in the physical world.
